(11) Earnings Per Share

The share and net income per share data for all periods presented are based on the historical weighted‑average shares outstanding. The diluted earnings per share calculations show the effect of the weighted‑average RSUs outstanding and certain performance stock units ("PSUs") from our equity incentive plans as discussed in note 13.

The following table summarizes the nonvested stock that was outstanding but not included in the computation of diluted earnings per share because their inclusion would have had an anti-dilutive effect:


	Fiscal Year Ended
	2017	2016	2015
Nonvested stock	2,082	2	1,243

PSUs are not included in the diluted earnings per share calculation until the performance-based criteria have been met. See note 13 for further discussion of PSUs.
